For Loop in Apple Swift

Question

Apple\'s newly released language Swift has an example on the official documentation. Example is like this;

let interestingNumbers = [
    \"Prime\": [2, 3, 5, 7,         


        

Answer 1

for (kind, numbers) in interestingNumbers{}

This for loop actually enumerating the key/value pairs of dictionary interestingNumbers. Where kind is the key and numbers is the correspoding value

kind:Prime       //Key
numbers: [2, 3, 5, 7, 11, 13] //Value  

Here the complete solution of the exercise

let interestingNumbers = [
    "Prime": [2, 3, 5, 7, 11, 13],
    "Fibonacci": [1, 1, 2, 3, 5, 8],
    "Square": [1, 4, 9, 16, 25],
]
var largest = 0
var type: String = ""
for (kind, numbers) in interestingNumbers {
    for number in numbers {
        if number > largest {
            largest = number
            type = kind
        }
    }
}
largest
type
